Detection Guidance

Detection of this Cross Site Scripting (XSS) vulnerability in the HurryTimer WordPress plugin involves identifying if the plugin version is 2.14.2 or earlier, as these versions are vulnerable.

Since the vulnerability requires user interaction and involves injection of malicious scripts, one way to detect it is by scanning for suspicious script injections or unusual HTML payloads in the web pages generated by the plugin.

Specific commands are not provided in the available resources, but common approaches include:

• Checking the installed plugin version via WP-CLI: `wp plugin list` to verify if HurryTimer is installed and its version.
